Enzymes Homework Worksheets

The topic of enzymes and the chemical reactions of the cell is of great importance when teaching a class in biology or life science. Without enzymes, cells could not survive. The key to success in teaching this topic is to provide good instruction followed by a good review exercise. This document (printable and digital) is a 5 page student worksheet consisting of 44 questions. Diagrams and images are included to ensure student understanding of these concepts. As I teach my unit on enzymes, I assign a portion of these questions for homework each night. This document provides quality homework assignments and ends up being a completed and thorough study guide for the unit test. Choose to use the traditional printable version, or the paperless, digital Google Apps version.

What is included in this resource?

• Editable and Printable 5-page student handout
• Paperless Digital Version (not editable) for use in Google Drive, Google Classroom, and /or Microsoft OneDrive
• Teacher Guide and Answer Key
• Google Apps Teacher Guide

This worksheet of homework questions was written to go along with my Powerpoint on this same topic: Enzymes and the Chemical Reactions of the Cells PowerPoint and Notes.

Topics covered are:

• The role of chemical reactions in the cell, definitions of chemical reactions, reactants, and products.
• Energy in reactions, the breaking and forming of chemical bonds, the absorbing and releasing of energy during biological reactions.
• Activation energy
• Energy Absorbing Reactions
• Energy Releasing Reactions
• What are Enzymes?
• The Essential Role of Enzymes in Living Cells
• Enzymes make reactions take place faster and at a lower temperature.
• Enzymes lower the activation energy of a reaction.
• Comparison of enzymes and catalysts.
• How enzymes work, equation showing the role of enzymes in a chemical reaction, substrates, active sites, enzyme-substrate complex, new products.
• Students will label a diagram of an enzyme-catalyzed reaction.
• Summary of the facts about enzymes.
• Factors that affect the functioning of an enzyme: Temperature and pH.
• Denatured enzymes.

All answers are included in the additional 5 page teacher guide that is included with this product.

The questions are of varying difficulty levels. Question types include compare and contrast, fill in the blank, short answer, multiple choice, labeling and true/false. You will receive both a Word document as well as a pdf form of the study guide. Many of the questions are basic and concrete in nature, but many of the questions involve critical thinking and problem solving skills.
